Algebraic expressions (Part 1)INTRODUCTION TO ALGEBRAConsider the expression below and answer the questions that follow:−2b+5−x4−3y−2𝑏+5−𝑥4−3𝑦Answer:How many terms are there in the expression? What is the value of the coefficient of y𝑦? What is the value of the constant term? 2 attempts remaining
Solution
The given expression is: −2b + 5 − x/4 − 3y
-
The number of terms in the expression: An algebraic expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables. Each term in an algebraic expression is separated by a + or - sign. In this case, the expression has four terms: -2b, 5, -x/4, and -3y.
-
The coefficient of y: The coefficient is the numerical factor of a term that contains a variable. In the term -3y, the coefficient of y is -3.
-
The value of the constant term: The constant term in an algebraic expression is the term without a variable, which is 5 in this case.
